Bus Bar Insulation

I thought it would be a good idea to use some shrink tube on the bus bar to help eliminate anything hitting it and shorting something out.  I used the ⅛” bus bar between the starter and master solenoids and 1/16″ on the other two.  I wouldn’t have been able to bend the ⅛” in that short area.  I’ll have to remove the ones on the shunt to be able to get to the two small screws to attach the other wires, but this way everything can stay in one place for now.
